I am also having the same problem. I have an IBM Think Center and the only device appearing in device manager is the High Definition Audio Device. I have another PC which has also been upgraded and the sound driver is working. It is using a SoundMax Integrated Digital HD Audio. Both PCs are the same make and model.

I have a way around this, download the hp softpac number SP32593, for the nx7400 anyway. download the softpac and run it, and then close it down when it errors on you.

go in to the device manager01. start menu 02. right click on "Computer"03. click on manage04. user account control opens up, click OK05. left hand pane of the "computer management" console06. double click on the "Sound, Video and games controllers" bit07. right click on the HDAudio blah blah blah bit08. click ont he update driver software09. click browse my computer for software10. click broswe11. navigate to the area that the softpac was unpacked to ...normally C:\SWSetup\SP32593

within that go to the SMAXWDM folder and then the w2k and xp folder and click ok, paths should look something oike this "C:\SWSetup\SP32593\SMAXWDM\W2K_XP"

click on next...bobs your uncle and it should install it...well worked for me a few mins ago, hope this helps any one with problems, mail me @ adam_way@msn.com if u need more help, i will always try.

I too had the NO SOUND issue and it was driving me crazy . I read several post here about the sound problem. I too had a red X by my speaker icon and no sound. I downloaded the driver several times for SoundMAX Integrated Digital HD Audio. It did no good; my system would not recognize the driver. The error message from the red X continued to say I had no Audio device loaded. Rrrrrrrrr!

I called HP support. After an hour and a half and three Indian foreign specialist, I was told that they knew of the problem and it was a Microsoft support issue, not their HP machine. They stated that there was not yet a driver out for Vista. Go figure huh? You gotta love those Indian guys.“tank you vedy much”.

I went to the driver section so I could look at the list to draw from. I chose the “Browse for driver software on your computer”. When I went to that screen, instead of hitting the browse button I chose the option below called “Let me pick from a list of device drivers”. When I was brought to the next screen there were two drivers to choose from. I saw my driver and tried that one. Rats, it still did not solve the problem. I repeated the steps above and chose the other driver instead, I chose the

‘High Definition Audio device”. I got a warning that it was not a correct copy and it might cause instability I figured this was the driver for the HDTV devise but I chose it anyway. The red x went away from my speaker icon which was progress but still no sound.

I then repeated the steps aboveproceeded to RE-LOADED my SoundMAX Integrated Digital HD Audio driver. The system told me to reboot. I did… and gentlemen, I had sound. My music never sounded so good.

I believe the problem is that if your system thinks you have the correct driver, it does not reload it. But by changing drivers then going back to the original driver, it forced the system to re-load it. Who knows, after all, I am not a certified geek (Just a closet geek).

Same situation with me. Thinkpad T61, but I have the "p" model. Took your advice and used "add/remove programs", but selected change instead of uninstall, then was presented with the reinstall option in the SoundMAX installshield applet. This seemed to work, but the installshield applet won't close... Interesting.

Also, once I killed the SoundMAX installshield program, the Add/Remove applet was still running, and when I attempted to close it, it would not close. It appears to be a zombie-like process...can't minimize or maximize, can't move it, can't close it. Since I'm not sure what the process name is for the Add/Remove applet, I can't end its process.
